Question 230
During a regulated deployment assessment at a healthcare imaging provider, engineers report the following issue: A training operation multiplies large matrices but only one CPU core is used. The affected work supports clinical imaging and model-assisted workflows; patient data constraints and reliable model performance are important. Which TWO responses form the best remediation-and-evidence pair? (Select TWO.)
Explanation
Correct Answers
Correct corrective action. Select a GPU for many data-parallel numerical operations and a CPU for branching control or low-parallelism tasks, considering end-to-end bottlenecks. This fits the specific reported issue: A training operation multiplies large matrices but only one CPU core is used. The corresponding failure being reduced is: Running inherently sequential orchestration on a GPU can add overhead, while running massive independent tensor operations solely on CPU can underutilize available parallelism.
Correct independent evidence. A measured workload shows meaningful end-to-end speedup for parallel computation while the host still handles control and scheduling. This verifies the corrective approach for the affected clinical imaging and model-assisted workflows instead of treating an architecture diagram alone as success.
Incorrect Answers
Not the most direct the action-and-evidence pair for these facts. Associate NVIDIA Omniverse and simulation or digital-twin workflows with designing and validating spatial industrial scenes, not with GPU health metrics or simple model-serving APIs. This choice concerns nvidia omniverse industrial simulation workflows and may be valid in another design. But this case reports 'A training operation multiplies large matrices but only one CPU core is used', which calls for reasoning about gpu parallel throughput versus cpu serial control. The targeted response is: Select a GPU for many data-parallel numerical operations and a CPU for branching control or low-parallelism tasks, considering end-to-end bottlenecks.
Not the most direct the action-and-evidence pair for these facts. The chosen supported model exposes the expected inference API on compatible hardware and meets the required latency and correctness smoke tests. This choice concerns nvidia nim inference microservices and may be valid in another design. But this case reports 'A training operation multiplies large matrices but only one CPU core is used', which calls for reasoning about gpu parallel throughput versus cpu serial control. The targeted response is: Select a GPU for many data-parallel numerical operations and a CPU for branching control or low-parallelism tasks, considering end-to-end bottlenecks.
Not the most direct the action-and-evidence pair for these facts. Consider supported Tensor Core acceleration and suitable reduced-precision formats for matrix-heavy deep learning, verifying accuracy and throughput for the specific model. This choice concerns tensor cores and mixed precision numerical tradeoffs and may be valid in another design. But this case reports 'A training operation multiplies large matrices but only one CPU core is used', which calls for reasoning about gpu parallel throughput versus cpu serial control. The targeted response is: Select a GPU for many data-parallel numerical operations and a CPU for branching control or low-parallelism tasks, considering end-to-end bottlenecks.
